WILLIAM .aDDLETorL or MOTTVILLE, NEW YORK'.

Letters Patent No. 92,139, dated'July 6, 1869.

IMPROVEMENT lIN HARROW AND MARKER COMBINED.

How-

The Schedule referred to in these Letters Patent and making part of the same.

. drawings, forming part of this specification, in which- Figure l is a plan view of my invention, and Figure 3 is a side view of the same. Figures 2 and 4 are detail views.

Similar letters of reference indicate like parts in v the several figures.

The body of this barrow is formed by a series or network of links, c, with spikes or barrow-teeth upon their lower sides, and by a Yseries of horizontal linksl or rings, b, for connecting said spike-links to each other, and in this manner a harrow is obtained of such ilexibility, that it will adjust itself to uneven surfaces with greater readiness than ordinarily.

In the accompanying drawings- A, iig. 1, is the front spreader, which is made strong` enough to hold the front edge ofthe barrow extended rigidly, and to this spreader the double-tree or whifiletrees are attached.

B B4 are elastic spreaders or stretchers, which are made thin, as seen in edge View, iig. 2, so as to yield with the harrow to the uneven surfaces of the ground.

C isa bar, having markers D D D attached, and said bar or marker is secured to the barrow in a detachable manner, by means of hooks or links f, and'` when going over the ground the last time with the harrow,

the marker is attached, andwhen the working of the ground is completed, it is already marked.

For dragging, the barrow is turned over, spikes upward, and the links made to pulverize the lumps, but when so used, the elastic spreaders B B are removed.

I do not wish to contine myself to the particular construction and arrangement ofthe links forming the body of the harrow, as the spike-links c' c may he omitted, and plain links substituted, for the reason that the spikes or teeth c are drawn in a direction sidewise t0- their links, and yield too readily by the rolling of' said links.

I do not claim, broadly, a barrow or barrow-frame, composed 0f links joined together and forming chains,

as I am aware that such. is not new ,but having thus described my invention, l

What I'clai-m as new, and desire to secure by Letters Patent, is

l. A flexible 'barrow-body, composed of chain or links b c c', with teeth attached, substantially as anl for the purpose herein described.

2. The removable stretcher-bars B B, made elastic or flexible, when constructed, arranged, and applied 'substantially as and for the purpose set forth.,v

3. The bar C O, with markers D, when adapted to be detached, in combination with a barrow-fratrie composed of chain-links, substantially as herein described.

The above speciiication of my invention signed by me., this 11th day of May, 1869.

A WILLIAM ADDLETON.
